6 Drawing Figures WALL FORM This invention relates to a wall form structure and particularly to a form for building dividing walls, swimming pool walls, silo walls, retaining walls and like structures. The wall form of the present invention greatly reduces the cost of plaster or concrete walls and materially simplifies construction of such walls. Wall forms are old and well known in the art. The forms are generally constructed of wood and the construction re quires the use of highly skilled labor, causing a resulting increase in the total cost of the walls and structure formed thereby. Equally significant is their high cost of removal and reinstallation. As a result of the high cost, plaster walls, for example, are seldom used as partitions or dividers in office buildings, although their superior sound absorbing qualities are well known.-

The present invention provides a novel and significant improvement over the present method of construction of wall considering forms. The invention provides a wall form easily constructed by unskilled labor in a very short period of time. Construction of the wall forms requires only the use of the simpliest of tools and relatively inexpensive materials. In a preferred form of our invention we provide a plurality of elongated first metal straps having spaced non-circular openings, a plurality of elongated second metal straps having like noncircular openings in a direction transverse to that of the first strap and a plurality of spacers having noncircular end portions engaging said openings of the first and second straps to form a grid. In the foregoing general description, we have set out certain purposes, ob-

jects and advantages of our invention.

It will be described hereafter and will become apparent for those skilled in the art of the construction of wall forms when consideri g the following description in the drawings in which:

FIG. I is a plan view of a first elongated metal strap used in this invention;

FIG. 2 is a plan view of a second elongated metal strap used in this invention;

FIG. 3 is a cross-sectional view of a portion of the wall made according to this invention;

FIG. 4 is a plan view of a wall made according to this invention;

FIG. 5 is a perspective view of the horizontal spacers used in this invention; and

FIG. 6 is a sectional view on line VV of FIG. 4.

' Referring to the drawings, we have illustrated in FIG. I, one form of an elongated metal strap for use in our invention. The form is made up of a strap 10 having spaced apart elongated openings 11 with the long axis of the opening parallel to the sides of the strap. In FIG. 2, we have illustrated a second form of elongated metal strap 12 with spaced apart elongated openings 13 with their long axis transverse to the sides of the strap. In each of straps l0 and 12 there are provided openings 11a and 13a between the slots 11 and 13 respectively. In FIG. 3, we have illustrated metal straps 12 in a vertical alignment afiixed to horizontal straps 10 by a spacer member 15 having elongated flattened ends 16 with parallel chordal flats l4 and 14 diametrically opposed to each other or alternately by cic'umferential grooves. Strap I2 is disposed vertically in relation to the floor and strap 10 is disposed horizontally in relation to the floor. FIG. 4 shows one face of the wall of FIG. 3 in which successive metal straps 10 are affixed to each other by means of screw 30 which is inserted in openings 11a. Metal straps l0 and 12 are affixed to spacers 15 by means of holes 11 and 13 engaging lands or grooves 14 and 14. The construction is then repeated until a wall frame of desired dimension is completed.

The horizontal spacers 15 (FIG. 5) are tubular mem bers and may be made of steel or like metals. In each end of the horizontal spacer a wooden or plastic member 20 can be inserted.

Gnce both faces of the wall are completed by repeating the construction described above, metal lath is attached to the form by, for example, inserting nails through the lath into the wooden member 20 inserted into the spacers .15. The gauge and strength of the metal straps, spacers and lath is determined by the type of wall that is being constructed. Once the metal lath has been attached to the wall form, plaster or concrete can then be applied to the lath in the well known manner.

Thus, a wall form is constructed inexpensively and quickly without the need of skilled workmen and special tools.

In the foregoing specification we have set out certain preferred embodiments of our invention, however, it will be understood that this invention may be otherwise embodied within the scope of the following claims.

We claim:

1. A wall form comprising, spaced grids each formed of aplurality of elongated first straps having spaced non-circular openings, a plurality of second elongated straps, said straps having spaced non-circular openings in a direction transverse to those of the first straps, said first plurality of straps being overlaid transversely across said second plurality of straps with their respective non-circular openings in alignment and a plurality of spacer members having non-circular end fastening portions, each of said non-circular end fastening portions passing through the non-circular openings of transversely overlaid elongated straps of each of said spaced grids and having a portion larger than the smallthe elongated first and second straps are metal.
